BURNER.

Specification of Letters Patent.

Patented Mar. 2, 1915.

Application filed June 1, 1914. Serial No. 842,204.

T all whom it may concern:

Be it known that I, FRANK ANTONUCGIO, citizen of the United States,residing at Oakland, in the county of Alameda and 'State of California,have invented certain new and useful Improvements in Burners, of whichthe following is a specification.

The present invention relates to certain new and useful improvements ingaseous fuel burners, and more particularly to that type of burnerswhich are designed for use in connection with water heaters, the ob' ectof the invention being to provide a device of this character whichembodies novel features of construction whereby it can be readily takenapart and cleaned.

A further object of the invention is to provide a gaseous fuel burnerwhich is comparatively simple and inexpensive in its construction, whichwill not become clogged by drippings, which can be quickly assembled ortaken apart, and which will operate in an effective manner.

With these and other objects in view, the

novel combinations and arrangements of the parts as will more fullyappear as the description proceeds, the novel features thereof beingpointed out in the appended claims.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawing, in which Figure 1 is atop plan view of a gaseous fuel burner constructed in accordance withthe invention. Fig. 2 is a vertical sectional view through the burner onthe line 22 of Fig. 1. Fig. 3 is a plan view of the large burner ring,showing the same as detached from the burner. Fig. 4 is a side elevationof the same. Fig. 5 is a view similar to Fig. 3, showing the smallburner ring. Fig. 6 is a plan view of the central burner plate. Fig. 7is a plan view of a gaseous fuel burner, showing a modified form of theinvention. Fig. 8 is a vertical sectional view on the line 88 of Fig. 7.Fig. 9 is a detached plan view of'the outer burner ring used in themodified form of the invention. Fig. 10 is a side elevation of the same.Fig. 11 is a detached plan view of the inner burner ring used in themodified form of the invention. Fig. 12 is a plan view of the centralburner plate used in the modified form of the invention.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Specifically describing the preferred embodiment of the invention,thenumeral 1 designates a burner pan which has a shallow formation andis formed with an outwardly inclined peripheral side wall 2. A suitablefeed pipe 3 communicates with the burner pan 1, said feed pipe beingshown as provided with conventional air inlet openings and a nipple 5for connection with a gas pipe.

Arranged within the mouth of the burner pan 1 are two annular burnerrings 6 and 7, together with a central burner plate 8, said membersbeing formed with outwardly inclined side walls which cooperate witheach other and the outwardly flared sides 2 of the pan to providesupporting means for holding the members in position. The burner ring 6is formed with an outer peripheral flange 6* and an inner peripheralflange 6*, both of said flanges being flared outwardly and the outerflange 6 resting v against and engaging the sides 2 of the burner pan tosupport the ring 6 in position. In a similar manner the inner burnerring 7 is formed with an outer peripheral flange 7 and an innerperipheral flange 7, both of which are inclined outwardly, the outerflange 7 bearing against and engaging the inner flange 6 of the ring 6to support the burner ring 7 in position. Arranged within the ring 7 isthe .central burner plate 8 which is formed with a peripheral upwardlyproecting and outwardly inclined flange 8", said flange engaging theinner flange 7 of the inner burner ring 7 to support the plate inposition. This. central burner plate 8 is connected to the bottom of thepan 1 by means of some detachable fastening member such as the bolt 9.hen this bolt is in position the two burner rings and central burnerplate are held securely against displacement and the parts are heldrigidly in an assembled position, although after the bolt has beenremoved, the various parts can be lifted out of position so as to beeasily cleansed.

The outer inclined flange 6 of the burner ring 6 is formed with a seriesof upright ribs 10 which fit within corresponding depressions 11 formedin the inclined sides 2 of the pan 1. It will also be observed that theouter faces of the ribs 10 are formed openings.

' grooves providing a with semicircular longitudinally disposed 1' willbe observed that the outer flange 7 of the smaller burner ring 7 isformed with ribs 14 adapted to be received Within correspondingdepressions 15 in the inner flange 6 of the burner ring 6, the said ribsand depressions being provided with the corresponding grooves 16 and 17respectively which cooperate with each other to provide burner openings.observed that the-flange 8 of the central plate 8 is formed with ribs 18adapted to be received within corresponding depressions 19 in the innerflange 7 of the burner ring 7, said ribs and depressions being formedwith the corresponding grooves 20 and 21 which cooperate with each otherto provide an inner annular series of burner As indicated upon thedrawings, the periphery of the larger burner ring 6 may also be providedat suitable intervals with positioning and supporting lugs 22 adapted toengage suitable seats 23 in the side walls 2 of the burner pan.

When the several burner rings and central plate are assembled within themouth of the burner pan, the cooperating inclined walls of the membersprovide a supporting means for retaining them in position while thecorresponding ribs and depressions bring about an interlockingconnection between the members, the corresponding series of, annularrows of burner openings. The members can be easily lifted out ofposition after the bolt 9 is removed, so that the burner can be easilyand thoroughly cleansed at any time. It will also be observed that eachof the rings 6 and 7 is constructed to provide an annular trough whilethe central burner plate 8 provides a pocket, the troughs and centralpocket being adapted to catch and collect drippings from the boiler sothat they will not find their Way into the interior of the burner andinterfere with the proper action thereof.

Figs. 7 to 12 inclusive of the drawing serve to illustrate a modifiedform of the invention. The numeral 24 designates a burner pan which, asin the previous instance, is formed with a peripheral ,out-

wardly inclined side wall 25, and communi cates with a fuel supply pipe26. Arranged within the mouth of the pan are the concentrio burner rings27 and 28, together with the central burner plate 29 The outer burnerring 27 is formed with the outer peripheral flange 27 and the innerperipheral It will further be flange 27", the latter having only afraction of the height of the former, although they are both, outwardlyinclined and the outer flange engages the inclined side wall 25 oftheburner pan to support the ring in position. In a similar manner theinner burner ring 28 is formed with an flange 28 and an inner peripheralflange 28", the latter being shorter than the former, and the outerflange 28 engaging the inner flange 27 b of the ring 27 to support thering in position. The central burner plate 29 is formed with aperipheral and outwardly inclined flange 29 which engages the innerflange 28 of the ring 28 to support the plate 29 in position. Theflanges 29, 28 and 27 are of substantially the same height and arepreferably higher than the flanges outer peripheral 27 and 28 which arealso of substantially the same height. It will also be observed that theflanges 29, 28, and 27 are provided on the outer faces thereof with theupwardly extending. grooves 30 which 'cooperate with the'walls orsurfaces of the members against which they lit to provide burneropenings leading the top of the burner. As in the previous from the pan24 to l instance the burner rings provide troughs" while the centralburner plate provides a pocket for the purpose of collecting drippingsand preventing them from passing into the interior of the burner in sucha manner as to interfere eration thereof. 7
